Our 299RC, which studies cats, was researching fish with high nutritional value for cats. Our research revealed that ancient fish have abundant nutritional reserves that do not exist in modern fish. However, no one has ever raised a fish, much less a fish with a nihilistic face that has no idea what it is thinking... The researchers are a group of cat experts. No one knows how to raise a fish... The institute has decided that it is impossible to raise this nihilistic fish as it is! So, we need your help. We need your help in researching this nihilistic fish "BasPi". Right now, we can only provide a simple tank, common fish food, and an environment like that... As our research progresses, we will be able to add more equipment. Until then, please keep this "BasPi" alive and pass it on from generation to generation. In this tank, there are sometimes mysterious creatures that are after the "BasPi". Normally, this type of fish should be armored, but this "BasPi" is fluffy and unreliable. I have prepared some equipment for just in case. You will not be able to use them until you become an adult, but I hope that somehow you will survive the crisis with this equipment. Thank you very much. *This story is a work of fiction.

Verdict
The clearest difference is in-app purchases: 虚無魚BasPi! at none against GAtsume's 1. 虚無魚BasPi! also leads on device support (3 vs 1) and iOS requirement (15.0 vs 18.6). GAtsume's advantage is ads (none vs shown) and update cadence (every 2 days vs every 4 weeks). On price there is nothing between them.
